- IMPRovEMENT IN GATES.

The Schedule referred to ln thee'ietters Patent and making pari. ol' thename.

I, URIAH W. HARDY, of Abingdon, 'in the countyof Knox and State ofIllinois, have invented .certain Improvements in Gates, of which thefollowing is a specilication- Nature and Objects of the Invention.

The nature of my invention relates to improvements in that class ofgates known as folding-bar gates, 'in which the bars fold up and assumea vertical position when the gate is opened l; and the inventionAconsists in the combination bf a stay with the pivotposts andoperating-levers, so constructed as to allow of the free working of' thelevers, as required, and at 'the same time keep the levers in place, allas hereinembodying my invention, and representing the gatel clgsed.

Figure 2 lis a perspective view of a gate complete, embodying myinvention and representing the gate open.

General Description. Letters A represent the horizontal gate-bars.

Letters B represent the cross-bars.

C is the latch-post, with ledges c c c c, at its upper and lower ends;to form guides for .the end of the gate while -opening and closing, andstays, when the gate is shut.

D D are the pivot-posts or side-posts,

E E are the operating-levers." i vl? E are posts, on which the levers EE are pivoted. l

G is a stay, attached to and projecting upward from the side of one theposts D, and its upper part inclined, as shown in the drawing. i

H is the latch, pivoted on the upper side of the upper horizontal bar,by hinges I I, either on top of the said bar with a stop-pin at its rearend, or in a suitable place cut in the bar, as shown-in the drawing, sothat when 'the latch is drawn back its rear end will 'strike theshoulder a; i

`The lhinges I I are attached, as shown plainly, so

that, when the latch His drawn back, the hinges still incline forward,kin order that when the latch is released 'and in a horizontal positionit will drop downwardand forward by the force of its own gravity, andengage with any suitable recess iu the post O.

The adjacentends of the levers. EE areconnected by a ring, e, andstaples c'c'.

J is a chain, extending from the :ring c to the staple h, ou the rearend ot' the latch H.

K is a chain, connecting the adjacent ends 'of' the levers E E with thetop bar A, at a point alittle ,forward of the point at which the bar Ais pivoted in the posts D D.

- to the edge ofthe posts D D, as 4shown by the dotted lines at g. 1,"toassist in holding the gate aslast de- L is a weight on the bar A, whichis extended for its attachment in the usual manner in this class ofgates, land. is so poised that the weight and gate balance each theother when the gate stands at an angle of about vseventy degrees;passing which in closing p the gate will close itself, and passing whichin opening it will open itself. p

The posts C D D F F, may beset in the ground, or they may be set in aframe, M. v

The construction and operation are as follows:

The bars A are pivoted on a slope line, between the posts D D, at thepoints a wa a a a af a so that they may stand side by side when the gateis open, and their. lower ends rest between the posts/D D, holding the`gate iirmlyagainst wind, or vibration sidewise, from any cause, whileopen and while being opened.` v

Iheends ofthe upper bars A A A A AA, are eX- tended back past theirpivoted -points a.' a a a a a',

scribed.

Iuopening the gate, the personv approaching it takes. hold'of the freeend of one of the levers E, which are pivoted loosely ou top of theposts F, and, drawing it slightly horizontally, releases or draws backthe latch H by the chain J then by drawing the same end of the lever Evdownward the chain K will raise the gate to the angle of seventydegrees, passing which it will, with `the aid of the momentum acquired,carry itself to a vertical position.

In closing the gate the outer end of either lever E isthrown backhorizontally, and its other end striking the upper gate-bar A, willcarry it past the inclination of seventy degrees from the horizontal,from which point it will close itself.

'llo enable the levers E to have side motion suiicieutly in closing thegate, the upper end of the-,stay

.G is inclined, as showu plainly at figs..1 and 2, and

when the gate is open the ends ofthe levers E E, adjacent to.each other,are brought up opposite said incline. When the gate is closed the saineends of the levers drop to the vertical part of the stayI G, which holdsthem in position for convenience in reaching by the approaching horsemauor other person.

. Claim.

yI claim as my invention- The stay G, when constructed as described,with an inclined top, and combined with the posts D, levers E E, and barA, substantially as described, and for the purpose specified.
